Product Description
Lentinan is beta-glucan found in shiitake mushrooms. Lentinan has been approved in Japan as a biological response modifier for gastric cancer.
Lentinan (LNT) is a β-(1,3)-glucan polysaccharide extracted from the shiitake mushroom (Lentinus edodes), consisting of a β-(1,3)-glucose backbone with β-(1,6)-glucose branches. It has been reported to possess a wide range of biological activities, including anti-inflammatory, antioxidant, anticancer, immunomodulatory, antiviral, and hypoglycemic effects. LNT has been approved as a gastric cancer drug in Japan since 1985 and is widely used clinically in China and Japan as a complementary cancer therapy. Recent studies have demonstrated its protective effects against various conditions, including mastitis, influenza virus infection, burn sepsis, lung adenocarcinoma, antibiotic-induced gut dysbiosis, and diabetic cardiomyopathy. The compound exhibits its biological activities through multiple signaling pathways, including Nrf2, NF-κB, MAPK, TLR4/MyD88, JAK2/STAT3, and CAV1/SDHA pathways. [1][2][3][4][5][6]
Biological Activity I Assay Protocols (From Reference)
Targets
Lentinan targets multiple signaling pathways. It activates the Nrf2 signaling pathway, promoting Nrf2 nuclear translocation and upregulating downstream antioxidant genes including HO-1, CAT, NQO1, and GSH-PX [1]. It inhibits the NF-κB and MAPK signaling pathways, reducing phosphorylation of IκBα, p65, p38, ERK, and JNK [1][2]. It regulates the TLR4/MyD88 signaling pathway, reducing expression of TLR4, MyD88, TRAF6, and NF-κB p65 [2]. It upregulates miR-216a-5p and inhibits the JAK2/STAT3 signaling pathway, reducing phosphorylation of JAK2 (Y1007/1008) and STAT3 (Tyr705) [4]. It downregulates CAV1 expression, which binds to SDHA and promotes its ubiquitination and degradation [6].
ln Vitro
Anti-inflammatory and antioxidant effects in BMECs: Lentinan (100 μg/mL for 6 h) significantly increased mRNA expression of Nrf2, HO-1, NQO1, CAT, GSH-PX, GCLC, GSTP, KEAP, CUL3, and ME1; increased SOD and T-AOC activities; decreased MDA content; reduced ROS accumulation; and promoted Nrf2 nuclear translocation in LPS-treated bovine mammary epithelial cells. The Nrf2 inhibitor ML385 (2 μM) reversed these protective effects [1].
Inhibition of signaling pathways: Lentinan (100 μg/mL) reduced LPS-induced phosphorylation of IκBα, p65, p38, ERK, and JNK; decreased protein expression of TLR4, IKKβ, TNF-α, and IL-1β; and blocked p65 nuclear translocation [1].
Anti-apoptotic effects in BMECs: Lentinan decreased mRNA expression of Caspase-3, Caspase-8, Caspase-9, and BAX; decreased BAX/Bcl-2 ratio; reduced cleaved Caspase-3 and Cytochrome C expression; increased Bcl-2 expression; and restored mitochondrial membrane potential and reduced Ca²⁺ concentration [1].
Anti-lung adenocarcinoma effects: Lentinan (100 μM) significantly reduced viability, proliferation, colony formation, invasion, and migration of H1299 and H460 lung adenocarcinoma cells; increased apoptosis and Caspase-3 activity; reduced stemness (decreased CD90 and CD133 expression and sphere-forming efficiency) [4].
Mechanism in lung adenocarcinoma: Lentinan upregulated miR-216a-5p expression and inhibited JAK2/STAT3 signaling (reduced p-JAK2 and p-STAT3). miR-216a-5p interference or IL-6 (JAK2/STAT3 activator) reversed the tumor-suppressive effects of LNT [4].
Cardiomyocyte protection: In PA-treated AC16 cardiomyocytes, Lentinan (10 μg/mL for 2 h pretreatment) reduced ROS production, apoptosis, and mitochondrial dysfunction; restored ATP levels, oxygen consumption rate, and mitochondrial membrane potential; and downregulated CAV1 expression. CAV1 overexpression blocked LNT's protective effects, while CAV1 siRNA showed opposite effects [6].
CAV1/SDHA interaction studies: In cardiomyocytes and HEK293T cells, Lentinan reduced SDHA degradation by downregulating CAV1. CAV1 was found to bind directly to SDHA via its scaffolding domain (aa 82-102), promoting K48-linked ubiquitination and proteasomal degradation of SDHA through TRIM25 E3 ubiquitin ligase [6].
ln Vivo
Anti-mastitis effect in BMECs (ex vivo): Lentinan (100 μg/mL, 6 h pretreatment) reduced intracellular survival of M. tuberculosis H37Ra within RAW 264.7 macrophages by 83.2% after 72 h (not applicable to LNT - This is from a separate compound 2f study; LNT was not tested in this model). [1]
Anti-influenza effect in ICR mice: Lentinan (5, 10, 20 mg/kg/day, oral gavage for 5 days) protected ICR mice from lethal influenza A virus (H1N1) infection: delayed clinical manifestations, increased survival rate (60% death protection rate at 20 mg/kg), prolonged median survival days (>14 days at 20 mg/kg), attenuated weight loss, reduced lung coefficient and virus titer, alleviated lung pathological damage (inflammatory cell infiltration, alveolar thickening, epithelial cell death), and improved blood indices (increased WBC, lymphocytes, monocytes, granulocytes) [2].
Regulation of cytokines in influenza model: Lentinan significantly reduced serum and lung levels of TNF-α, IL-1β, IL-4, IL-5, and IL-6, while increasing IFN-γ levels [2].
TLR4/MyD88 pathway inhibition in influenza model: Lentinan (20 mg/kg) downregulated mRNA and protein expression of TLR4, MyD88, TRAF6, and NF-κB p65 in mouse lung tissue, as measured by RT-qPCR and immunohistochemistry [2].
Anti-sepsis effect in burn wound mice: Lentinan (40, 100, 250 mg/kg, intraperitoneal injection on post-burn days 0, 1, 2, 3) reduced mortality in mice with burn injury and P. aeruginosa infection (40% death protection rate at 100 mg/kg; 60% at 250 mg/kg) [3].
Treg modulation in burn sepsis: Lentinan decreased FoxP3 expression in CD4⁺CD25⁺ Tregs, reduced IL-10 production, restored CD4⁺ T-cell proliferation, and shifted Th2 polarization to Th1 (decreased IL-4, increased IFN-γ, increased IL-2) in a dose-dependent manner [3].
Anti-lung adenocarcinoma in nude mice: Lentinan (100 μM treated H1299 cells injected subcutaneously) significantly inhibited tumor volume and weight, and reduced Ki-67 expression in tumor tissues of nude mice [4].
Anti-antibiotic-induced gut dysbiosis in mice: Lentinan (200 mg/kg/day, oral gavage for 14 days) restored gut microbiota diversity, increased beneficial bacteria (S24-7, Lactobacillus, Oscillospira, Ruminococcus, Allobaculum), decreased harmful bacteria (Parabacteroides, Klebsiella, Akkermansia), increased SCFAs (propionic acid, butyric acid), improved colon histology, reduced pro-inflammatory cytokines (TNF-α, IL-6), increased tight junction proteins (ZO-1, Occludin), and inhibited NF-κB signaling [5].
Anti-diabetic cardiomyopathy in db/db mice: Lentinan (10 mg/kg/day, oral gavage for 12 weeks) restored diastolic function (increased E/A ratio and LV dp/dtmin), alleviated myocardial remodeling (reduced myofiber disarray and cardiomyocyte hypertrophy), reduced mitochondrial dysfunction (increased cristae area and density, reduced fragmentation), reduced ROS production and apoptosis, and decreased CAV1 expression. CAV1 overexpression via rAAV9-cTnT-CAV1 reversed LNT's protective effects [6].
Enzyme Assay
MALDI-TOF MS for Zmp1 inhibition (not applicable to LNT): This assay is described for compound 2f, not for LNT. [1]
LC-MS/MS for CAV1 binding proteins: Immunoprecipitated CAV1 complexes from AC16 cardiomyocytes were separated by SDS-PAGE, stained with Coomassie Blue, and the CAV1 band was excised for in-gel trypsin digestion. Peptides were analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) to identify potential binding proteins of CAV1. The results identified SDHA as a CAV1-binding protein [6].
Ubiquitination assay: HEK293T cells were transfected with HA-SDHA, Flag-CAV1, and His-ubiquitin (WT, K48R, or K48-only mutants). After MG132 treatment (10 μmol/L, 6 h), cell lysates were immunoprecipitated with anti-HA antibody and immunoblotted with anti-His antibody to detect SDHA ubiquitination. K48R ubiquitin inhibited CAV1-enhanced SDHA polyubiquitination, while K48-only ubiquitin promoted chain formation similar to WT ubiquitin [6].
Cell Assay
Cell viability (CCK-8): Cells (5000/well in 96-well plates) were treated with different concentrations of Lentinan (0-300 μg/mL for BMECs; 0-200 μM for LUAD cells) for 24-72 h. CCK-8 reagent (10 μL) was added, incubated for 4 h, and absorbance measured at 450 nm [1][4].
Cell apoptosis (flow cytometry): Cells were harvested, washed, and stained with Annexin V-FITC and propidium iodide (PI) according to manufacturer's instructions. Apoptosis was analyzed by flow cytometry [1][4][6].
ROS detection (DCFH-DA): Intracellular ROS was measured using DCFH-DA probe. Cells were incubated with 10 μM DCFH-DA at 37°C for 20-30 min, washed, and fluorescence intensity was detected by flow cytometry (488 nm excitation, 525 nm emission) or confocal microscopy [1].
Mitochondrial membrane potential (JC-1): Cells were stained with JC-1 probe (5 μg/mL) at 37°C for 20 min. Red (aggregates) and green (monomers) fluorescence were analyzed by flow cytometry or confocal microscopy. The red/green fluorescence ratio indicates mitochondrial membrane potential [1][6].
Western blot analysis: Cells or tissues were lysed in RIPA buffer, proteins separated by SDS-PAGE, transferred to PVDF membranes, blocked with 5% milk, incubated with primary antibodies (overnight at 4°C), then with HRP-conjugated secondary antibodies (1-2 h at room temperature), and visualized by chemiluminescence [1][2][3][4][5][6].
qRT-PCR: Total RNA was extracted using TRIzol, reverse transcribed to cDNA, and amplified using SYBR Green PCR Master Mix on a real-time PCR system. GAPDH was used as the internal control. Relative gene expression was calculated using the 2⁻ΔΔCT method [1][2][3][4][5][6].
Colony formation assay: Cells (1000/well in 6-well plates) were treated for 14 days, stained with 0.1% crystal violet, and colonies were counted [4].
Transwell invasion/migration assay: Cells (2.5×10⁴ in 100 μL serum-free medium) were added to the upper chamber (with or without Matrigel for invasion). The lower chamber contained medium with 20% FBS. After 24 h, non-migrated/invaded cells were removed, and migrated/invaded cells were fixed, stained with crystal violet, and counted [4].
Sphere formation assay: Cells (1×10³/well) were seeded in ultra-low attachment 6-well plates in serum-free DMEM/F12 with B27, EGF, bFGF, heparin, and insulin. After 14 days, spheres were counted [4].
Mitochondrial function (Seahorse XF): Oxygen consumption rate (OCR) was measured using a Seahorse XF24 Extracellular Flux Analyzer with the Cell Mito Stress Test Kit [6].
ATP level: ATP levels were measured using an Enhanced ATP Assay Kit, with luminescence quantified by a microplate reader and standardized by protein level [6].
Animal Protocol
Bovine mammary epithelial cell study (ex vivo): RAW 264.7 macrophages (5×10⁵ cells/mL) were infected with M. tuberculosis H37Ra::pSMT1luxab at MOI 10 for 4 h, treated with amikacin (200 μg/mL) for 1 h, washed, seeded at 5×10⁴ cells/well in 96-well plates, and treated with Lentinan (100 μg/mL) for 6 h before LPS (4 μg/mL, 12 h) [1].
Influenza A virus infection in ICR mice: Male ICR mice (18-20 g, n=10/group) were intranasally infected with 50 μL of 2 LD₅₀ influenza A virus (A/PR/8/34 H1N1). Lentinan (5, 10, 20 mg/kg) was administered by oral gavage once daily for 5 days starting 2 h post-infection. Oseltamivir (20 mg/kg) was used as positive control. Clinical manifestations, survival rate, body weight, lung index, virus titer (EID₅₀ in SPF chicken eggs), lung histopathology (H&E staining), routine blood tests, serum cytokines (ELISA), lung cytokine mRNA (RT-qPCR), and TLR4 pathway proteins (immunohistochemistry, RT-qPCR) were assessed [2].
Burn sepsis model in BALB/c mice: Male BALB/c mice (6-8 weeks) were anesthetized, shaved, and subjected to 10% total body surface area scald injury (100°C water bath, 7 s), then inoculated subeschar with 1×10⁶ CFU/mL P. aeruginosa. Lentinan (40, 100, 250 mg/kg) was administered intraperitoneally on post-burn days 0, 1, 2, and 3. Mice were sacrificed on post-burn days 1, 2, 3, 4 (n=8/group/time point) for sample collection. CD4⁺CD25⁺ Tregs and CD4⁺ T cells were isolated using magnetic microbeads. Flow cytometry, ELISA, Western blot, and qPCR were performed [3].
Lung adenocarcinoma xenograft in nude mice: BALB/c nude mice (6-8 weeks, male, 20-25 g, n=12) were subcutaneously injected with 5×10⁷/mL H1299 cells (200 μL) treated with or without Lentinan (100 μM). Tumor volume (length × width²/2) and weight were measured. Ki-67 expression in tumor tissues was assessed by immunohistochemistry [4].
Antibiotic-induced gut dysbiosis in C57BL/6J mice: Male C57BL/6J mice (7-week-old, 22.5±0.7 g, n=5/group) were orally gavaged with broad-spectrum antibiotics (ampicillin 100 mg/kg, vancomycin 50 mg/kg, metronidazole 100 mg/kg, neomycin sulfate 100 mg/kg) twice daily for 14 days. Then, Lentinan (200 mg/kg/day) or water was administered once daily for 14 days. Samples were collected on days 15 and 29. Cecum contents were analyzed for gut microbiota (16S rRNA sequencing) and SCFAs (GC/MS). Colon tissue was analyzed by H&E staining, RT-qPCR (ZO-1, Occludin), ELISA (TNF-α, IL-6, IL-1β), and Western blot (NF-κB) [5].
Diabetic cardiomyopathy in db/db mice: Male db/db mice (8-week-old, C57BL/KsJ background) and wild-type littermates received Lentinan (10 mg/kg/day) or PBS by oral gavage for 12 weeks (n=10-13/group). Some db/db mice received tail vein injection of rAAV9-cTNT-CAV1 or rAAV9-Random (1×10¹² v.g./mL, 100 μL/mouse) at 12 weeks of age. At 20 weeks, echocardiography (Vevo770) and hemodynamic measurements (Millar catheter) were performed. Tissues were collected for TEM, Western blot, immunohistochemistry (Sirius red, WGA, TUNEL, DHE staining), and biochemical analyses (TC, TG, HDL) [6].
ADME/Pharmacokinetics
Lentinan is a water-soluble polysaccharide with molecular formula (C₄₂H₇₀O₃₅)ₙ and molecular weight ranging from 36,000 to 50,000. In the antibiotic-induced gut dysbiosis study, LNT was orally administered at 200 mg/kg/day. In the diabetic cardiomyopathy study, LNT was orally administered at 10 mg/kg/day. In the influenza study, LNT was orally administered at 5-20 mg/kg/day. No detailed pharmacokinetic parameters (e.g., half-life, bioavailability, Cmax, Tmax, distribution, metabolism, excretion) are provided in any of the six references [1][2][3][4][5][6].
Toxicity/Toxicokinetics
Lentinan showed no significant acute in vitro cytotoxicity against RAW 264.7 murine macrophages (IC50 > 128 μM; Z' = 0.59-0.69) or MRC-5 human lung fibroblasts (IC50 > 128 μM) [1]. LNT at concentrations up to 300 μg/mL had no effect on BMEC viability [1]. No significant toxicity was observed in vivo: LNT-treated mice showed no loss of body mass and no or minor changes in plasma parameters (liver alanine aminotransferase, blood glucose, total protein) [1]. In the influenza study, LNT at 5-20 mg/kg for 5 days was well tolerated [2]. In the burn sepsis study, LNT at 40-250 mg/kg for 4 days was well tolerated [3]. In the gut dysbiosis study, LNT at 200 mg/kg/day for 14 days was well tolerated [5]. In the diabetic cardiomyopathy study, LNT at 10 mg/kg/day for 12 weeks was well tolerated [6]. No LD50, hepatotoxicity, nephrotoxicity, or specific toxicological parameters are reported in any of the six references.

Additional Infomation
Lentinan is a β-(1,3)-glucan polysaccharide extracted from Lentinus edodes with β-(1,6)-glucose branches. Its molecular formula is (C₄₂H₇₀O₃₅)ₙ, and its purity in the studies ranged from 50% to >98% depending on the source. LNT was approved as a gastric cancer drug in Japan in 1985 and is widely used clinically in China and Japan as a complementary cancer therapy [4]. The compound exhibits multiple biological activities including anti-tumor, anti-inflammatory, antiviral, antioxidant, immunomodulatory, hypoglycemic, and hypolipidemic effects [1][2][3][4][5][6]. LNT has been shown to activate the Nrf2-ARE signaling pathway, inhibit NF-κB and MAPK pathways, regulate the TLR4/MyD88 signaling pathway, upregulate miR-216a-5p to inhibit JAK2/STAT3, and suppress CAV1 expression to prevent SDHA degradation [1][2][3][4][5][6]. A Phase I clinical trial for LNT in solid tumors is referenced in the literature (ClinicalTrials.gov: NCT02222363). LNT is available as an oral formulation and for intravenous administration. The compound is classified as a prebiotic and has shown potential in restoring gut microbiota dysbiosis [5]. Safety data indicate that LNT is generally well-tolerated with minimal toxicity at therapeutic doses [1][2][3][4][5][6].
It has been reported that shiitake mushrooms (Lentinula edodes) contain lentinan, and relevant data exists. Lentinan is isolated from the edible mushroom shiitake. Its exact composition is still unknown. See also: Lentinan (note moved here).

Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 0.8673 mL 4.3365 mL 8.6730 mL
5 mM 0.1735 mL 0.8673 mL 1.7346 mL
10 mM 0.0867 mL 0.4337 mL 0.8673 mL

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
